The efficacy of Bacillus subtilis SM21 on controlling Rhizopus rot caused by Rhizopus stolonifer in postharvest peach fruit and the possible mechanisms were investigated. The results indicated B. subtilis SM21 treatment reduced lesion diameter and disease incidence by 37.2% and 26.7% on the 2nd day of inoculation compared with the control. The in vitro test showed significant inhibitory effect ...

Invasive mycotic infections can be effectively treated if rapid identification of fungus is obtained. We reported a case of coinfection by Aspergillus and Rhizopus sp. involving nose, paranasal sinuses, orbit, and brain in a 68-year-old known hypertensive male. He was presented to ENT OPD with history of fever and intermittent headache since fifteen days along with history of right-sided nasal ...

BACKGROUND AND PURPOSE Soil is the main habitat of saprophytic and pathogenic fungi. Mucoromycotina constitutes a large group of soil fungi, with certain opportunistic members causing systemic infections in immunocompromised hosts. The majority of human and animal infections are caused by the members of the genera Rhizopus, Mucor, Rhizomucor, Lichtheimia (Absidia), Cunninghamella, and Mortierel...

The aim of the present investigation was to assess and compare the antimicrobial activities of the lemon (Citrus sinensis) peel extract and lemon oil against common food borne pathogens and to study their potential as food bio-preservatives. The antagonistic activity of lemon peel extract and lemon oil was studied against common food borne pathogens like Staphylococcus aureus, Staphylococcus ep...

Solid-state fermentation was carried out using brown rice (BR) and polished rice (PR) as substrates for the production of tempeh using a fungal culture of Rhizopus oligosporus. The rice based tempeh was further analyzed for its nutrient composition like carbohydrate, protein, fat, fiber and ash content. The prepared BR and PR tempeh samples were baked and its sensory qualities were evaluated. O...

GA (glucoamylase) hydrolyses starch and polysaccharides to beta-D-glucose. RoGA (Rhizopus oryzae GA) consists of two functional domains, an N-terminal SBD (starch-binding domain) and a C-terminal catalytic domain, which are connected by an O-glycosylated linker. In the present study, the crystal structures of the SBD from RoGA (RoGACBM21) and the complexes with beta-cyclodextrin (SBD-betaCD) an...

In the presence or absence of acetonitrile CH3CN, the molecular mechanism on the Rhizopus niveus glucoamylse (GA)-catalyzed reaction was studied by the steady-state kinetics for a substrate maltose (G2). At high concentration of G2, the GA-catalyzed reaction was observed not to obey the Michaelis kinetics and was reasonably explained with a mechanism of the substrate-inhibition involving the te...

Our objective was to obtain products of fusion of the filamentous fungus Rhizopus cohnii Rh.c./1 with an increased capacity for lipase biosynthesis in comparison with the original strain. Protoplasts of auxotrophic mutants of the parent strain Rh.c./1 obtained after UV irradiation of the spores were subjected to electrofusion. We found that the largest number of electrofusion products could be ...
